UNrrED STATES PATENT GEEICE.

OLE JAOOBSON GLASOE, OF LANESBOROUG-H, MINNESOTA.

IMPRovi-:MENT IN PLows.

Specitication forming part of Letters Patent No. 164,727., dated June22, 1875; application filed March 25, 1875.

To all whom it may concern:

Beit known that I, OLE J. GLAsoE, of Lanesborough, in the county ofFillmore and State of Minnesota, have invented certain new and usefulImprovements in Piows; and I do hereby declare that the following is afull, clear, and exact description thereof, which willenable othersskilled in the art to which it pertains to make and use the same,reference being had to the accompanyii'ig drawings and to the letters ofreference marked theron, which form a part of this specification.

My invention consists inthe combination, with a plow, of a device forpreventing the straw from piling` up under the beam, as hereinafter morefully described, and pointed out in the cla-ims. Y

Figure l is a side View of my improved Y plow, and Fig'. 2 is a rearview ofthe same.

Similar letters of reference indicate corresponding parts in bothgures.

A is the beam, B represents the handles, and O is the share. D is awheel or circular disk, made of iron, steel, or any other suitablematerial, and pivoted obliquely upon the arm a, forming part of theframe of the plow, back of the share, and mold-board. E is an endlesschain or band, moving round the anged pulleys IL` and e, and providedWith the clearers or cutters f. I prefer to have one or both of thepulleys 7L c provided with laterally-projecting teeth, `(shown at e inFig. 2,) which engage with the links ot' which the chain E is composed.The pulley bis operated by the vertical shaft d and pinion g, whichlatter engages with the teeth or cogs 7L, arranged concentrically uponthe wheel D, as shown. It'follows that when the wheel D rotates fromoperating the plow, the pinion g, shaft d, and pulley li will rotatealso, and

the chain `E, with its clearers, will move inf that are apt to pile upunder the beam, thereby greatlyimpeding progress and causing a greatwaste ot' power, are cut and cleared away, and my improved plow, whichhas in addition the benefit of the rotating land-side, may be operatedmuch easier, and with less expenditure ot' force, than plews asordinarily constructed Without this improvement.

Having thus described myinvention, Iclaim, and desire to secure byLetters Patent of the United States- 1. In a plow, the endless chain orband E, provided with the clearers j', substantially as and for thepurpose set forth.

2. The combination ot' the wheel or disk D, having theconcentrically-arranged cogs h, with the pinion g, shaft d, pulleys b c,and chain E, having cutters F, substantiallyas and for the purpose setfort-l1.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

OLE JAOOBSON GLASOE.
